What parameters are you passing to the popup? (There must be something–that’s the only way to make things different.)

Do you need to store the id variable anywhere? Or can you use it directly from entry field on popup?

Yes. They are called root container custom properties. Those are also the properties that can be filled in uniquely by the script that opens the popup (via parameters). Have you looked at the documentation for [system.nav.openWindowInstance](https://docs.inductiveautomation.com/display/DOC81/system.nav.openWindowInstance)?
